Police have launched an appeal for help to identify a man wanted for questioning after a reveller was knocked unconscious in a row outside a Wolverhampton bar.

Police need help to identify this man

The 33-year-old was attempting to diffuse an argument between a friend and door staff outside Jacks Café and Bar in Frederick Street when he was punched to the floor, hitting his head and losing consciousness for more than half an hour.

It happened just after midnight on Sunday March 9. The man who struck him was not employed by the club and so far attempts to trace him have been unsuccessful.

Dc Deb Dace said: "We are appealing for anyone who recognises the man in the CCTV image to contact us.

"As far as we can make out, he was not involved in the dispute and it is unclear why he intervened, so we would like to speak to him."

The man is described as black, around 5ft 10ins with short black hair and aged between 30 and 35. He was wearing a distinctive bright blue hooded jacket and carrying a bag with the strap worn across his body.

Anyone who recognises the man should call 101 or Crimestoppers anonymously on 0800 555 111.
